'0 (ZZZ IJJ/I/{HII/ 7125 nan/y concern;

Be it known thatI, GEORGE EVVOLFE, acitizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Rough-Rounding and Channeling Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an improvement in rough-rounding and channeling machines.

The object of the present invention is to reorganize and improve machines of the above class by providing such machines with a grooving-knife and mechanism whereby the channeling-knife may be thrown out of oper- 2o ation during any part of the operation upon a shoe-sole and the grooving-knife may be thrown into operation and, conversely, so that the grooving-knife may be thrown out of operation and the channeling-knife again thrown into operation.

Myinvention is particularly adapted for use in operating upon shoe-soles that are stitched aloft, and while I am aware that it has been proposed to provide a rough-rounding and 0 ehannelingvmachine with a channeling-knife which can be thrown out of and into operation during the continued operation of the machine my invention contemplates the employment in connection with a device of that character of 5 5 means for throwing the grooving-knife into and out of operation, so that the stitching aloft may lie in a shallow groove in the bottom of the sole, with the advantages well known to those skilled in the art.

A further object of my invention is to improve rough-rounding and channeling machines in other respects hereinafter pointed out.

To the above end the present invention consists in the devices and combinations of devices hereinafter described, and particularly defined in the claims.

' In the accompanying drawings, illustrating the preferred form of my invention, Figure l 5 is a sectional elevation of a portion of the rough rounding and channeling machines illustrated and described in Letters Patent of the United States granted to French and Meyer, February 22, 1898, No. 599,602, and March 22, 1898, No. 600,883, only so much of the machine of said patents being shown as is necessary for an explanation of my invention, reference being had to said patents for a disclosure of a machine with which the specific embodiment of my invention is particularly designed to cooperate. Fig. 2 is a plan of the parts shown in Fig. 1. Fig. 3 is a plan, Fig.

4 a front elevation, and Fig. 5 an end elevation, of the channeling-knife and its carrier. Fig. 6 is a side elevation. Fig. 7 is a bottom 5 plan of the slide for operating the groovingknife; and Fig. 8 is a plan, and Fig. 9 a side elevation, of the grooving-knife and its carrier.

The channelingknife 1 is mounted in a 7 suitable carrier, (indicated in a general way by the reference character 2,) which is slidingly mounted in a vertically-movable knife-carrier support 3. The grooving-knife L is mounted in a grooving-knife carrier 3, also slidingly mounted in theknifc-carrier support 3. The sole-rest 6 is revolubly mounted upon the knife-carrier support 3, which is carried by the carrier-block 7, carried in the usual way by the oscillating pivoted arm 8 of the ma- 3O chine of said patents. The knife-carrier support 3, the sole-rest 6, the sliding block 7, and the oscillating arm 8 are the same, except as hereinafter described, as in the machine of said patents. 5

The channeling-knife 1 is provided with a dovetailed shank 9, which is received in a correspondingly-shaped groove formed be tween the clip 10 and the body of the carrier 11, being secured therein by means of the 9 screw 12. The channeling-knife carrier 2 is provided with a dovetailed projection 13, which is received by acorrespondingly-shmaed recess in a projection 14: from the top of the knife-carrier support 3, extended rearwardly toward the left in adiagonal direction looking at the machine from the front. The upper side of the channeling-knife carrier 2 is provided with a pin 15, adapted to cooperate with a groove in the operating-lever hereinafter referred to. The above-described ar- IOC rangement is such that the channeling-knife carrier may be moved by its operatmg-lever from its operative position, as shown in Figs.

1 and 2, rearwardly along a path oblique to the line of cut that is to say, in the diagonal direction away from the sole of ashoe-so that it shall cease to cut a channel therein.

The grooving-knife 4c is provided with the dovetailed shank 16, which is received in a correspondingly-shaped groove in the grooving-knife carrier 5, being secured in proper position therein by means of the set-screw 17 The grooving-knife carrier 5 is received in a correspondingly-shaped hole 18 in the top of the knife-carrier support 3 and is adapted to reciprocate in said hole toward and from the front of the machine. Means are provided for moving the grooving-knife forward when the channeling-knife is withdrawn from operative position and for moving the grooving-knife backward when the channeling-knife is moved forward into operative position. Such means in the illustrated embodiment of my invention consists of a slide 19, provided on its under side with a diagonal slot 20, which engages a pin 21, projected upwardly from the upper side of the shank of the grooving-knife carrier 5. The reciprocations of the slide 19 impart corresponding reciprocations to the grooving-knife. The slide 19 is received in a slot 22, arranged at right angles to the hole 18, in which slot it is held by means of the plate 23, secured to the knife-carrier support 3 by means of screws. The slide 19 is provided upon its rear end with a pin 24, which is adapted to engage with the operating-lever hereinbefore referred to and which will presently be described.

It is to be noted that the channeling-knife and grooving-knife move in paths inclined to and intersecting each other and that their operative positions are substantially the same with relation to the sole-rest, projecting slightly beyond the surface of the sole-rest and at one end of the same.

cans are provided for retracting the channeling-knife and projecting the groovingknife, which means also operate to retract the grooving-knife and project the channelingknife. Such means in the illustrated embodiment of my invention consists of a lever 25, pivoted at 26 upon the projection 1a from the knife-carrier support 3. The lever 25 is provided with a slot 27, adapted to receive the pin 15, projecting upwardly from the upper side of the channeling-knife carrier, hereinbefore referred to. WVhen the lever 25 is turned about its pivot 26, the channelingknife carrier will be moved thereby either to retract the channeling-knife from its operative position or to project the same forward into operative position. The lever 25 is also provided with a cam-slot 28, which receives the pin 21, projected upwardly from the upper side of the slide 19, which actuates the groovingknife carrier. Inasmuch as the channeling-knife and the grooving-knife occupy substantially the same place when they are in their operative positions, the channeling-knife must first be withdrawn from operative position before the grooving-knife can be projected forward. The first part of the movement of the lever 25 must operate, therefore, to withdraw the channeling-knife from operative position. The slot 28 is therefore provided with an idle portion formed upon a curve of which the pivot-of the lever 25 is the center, so that this portion of the movement of the lever 25 is without effect upon the grooving-knife. As soon, however, as the channeling-knife has been retracted a short distance the grooving-knife may begin its forward movement, and in order to make this movement as rapid as possible the steep portion in the slot 28 is provided, which, engaging the pin 24, rapidly retracts the slide 19, said slide 19 operating by means of its groove 20 upon the pin 21 in the grooving-knife carrier to project the same forward into operative position. In order that the groovingknife may be held forward in its operative position, the slot 28 is provided with a further idle portion upon the opposite side of the steep portion above referred to, so that after the lever 25 has been turned so that the pin 24 occupies the right-hand end of the slide 28, as seen in Fig. 2, the slide 19 will be held from movement by said slot, and consequently the grooving-knife 1 will be securely held in operative position. During the latter part of the motion of the lever 25 the retracting movement of the channelingknife will be completed. Astop-pin 29, projected through the lever 25, engages a correspondingly-shaped hole in the projection 14 when the channeling-knife is forward in its operative position, so as to hold the lever stationary, thereby in turn holding the channeling-knife stationary in its operative position against the thrust of the knife during its cutting stroke. The stop-pin 29 is secured to the end of an auxiliary lever 30, pivoted at 31 upon the lever 25, so that the operator may grasp the two levers 25 and 30 between the fingers and by pressing them together against the action of the spring 32, which normally supports the lever 30 and tends to force the stop-pin 29 downward, so that it may engage its hole in the projection 14, he may lift the stop-pin out of its hole, thereby releasing the lever 25, whereupon he will push the lever rearwardly; whereby first the channeling-knife will begin to be withdrawn from its operative position and thereafter the grooving-knife will be moved forward into operative position and locked in such position. In order to withdraw the grooving-knife from operative position and to throw the channeling-knife into operative position, the operator will pull the lever 25 forwardly, thereby first withdrawing the grooving-knife from operative position and then forcing the channeling knife into operative position.

Then the stop-pin 29 Will drop into its hole and the parts Will be locked in the position shown in Figs. land 2.

Vhile l have described my invention in connection with the rough-rounding and channeling machine illustrated in the aforesaid patents, I donot intend to limit my invention to such specific embodiment, as the same may be embodied in other forms without departure therefrom.
